I helped a friend in reversing the firmware of some reciva internet radio module. Here are the results, explained in a few words he wrote down for interested readers.
Downloading from the Reciva Servers
Reciva has extended the open-source curl program for doing firmware downloads
(and possibly more) from its servers. They do not offer the source code [...]
hi,
since i dont find some spare time to update CEntrilo, i made the SVN public.
http://svn.g3gg0.de/svn/default/trunk/misc/CEntrilo/
username: centrilo
password: behave!
simply get the source, look how it works and create a new, CLEAN tool from it.
would be really cool if you can keep the core platform independent.
i also somewhen tried to make a symbian client, but could not get [...]
hi,
yeah, good news for you ;)
Although Luigi Auriemma said, he wont touch Ventrilo v3.0, he did it and released some code to authenticate with the servers. For you that means, there will perhaps be a CEntrilo v3.0 soon.
Thanks, mate!
But there are other (serious) things i have to do:
That CEntrilo code is ugly as hell! damn. its [...]
hi again.
just want to let you know that i will not support ventrilo v3.0.
the reason is, the ventrilo guys are authenticating the server against some of their servers.
just have a look at port 6100 when you start ventrilo…
as stated on: http://ventrilo.com/forums/showthread.php?t=23257
they require you to let the client authenticate the server.
if you are behind a firewall, [...]
well, first i want to thank the guy i wrote about there:
http://www.g3gg0.de/wordpress/archives/16
more than half a year later he contacted me and sent twice the money he promised before.
obviously he really was busy for long time ;)
thanks Mr. S.C. ;)
okay now about Ventrilo v3.0.x:
i had a look at the protocol. the connection setup is nearly [...]
yay…
i had some free minutes and wanted to catch up some changes i always wanted to make.
and since a friend was hacking around with 32bit ARM opcodes using stupid
“.dd E1234567″-opcodes, i knew its time to fix this. :)
it took some hmm 10 hours to implement nearly(!) the whole ARM32 instruction set.
now you can code [...]
okay, i didnt post very often in the last time – sorry for that ;)
but here some new screenshots showing my java-tool decoding the police radio frequency.
On the right side you see the connected processing modules like a squelch filter based on FFT, some AM/FM demodulator, a FIR filter to remove unwanted noise and a [...]
hi,
here some screenshot of the device in action:
well,
i didnt post much lately.
this is because im working on a little project for a Cypress CY7C68013A. thats a USB2.0 chip with a 8051 microcontroller for setup and firmware.
really an interesting project :)
won’t tell you exactly what its for, but its used to stream RF radio data with speeds up to 32MB/s to a Win32 [...]
yeah okay.
i released the latest version of the CEntrilo binaries for QVGA, VGA and MDA/XDA devices.
please test them – i just simulated them in the emulator.
you should see improved connection handling and better sound recording.
please report when you still see hangups after some time.
a guy asked me to fix all the problems and promised me [...]
